Abstract

This article presents the comparison between a quasi-switched boost inverter (qSBI) and a two-stage dc/dc-boosted inverter for photovoltaic applications. These two inverter topologies are compared based on their working modes, steady-state response, boost factor, voltage gain, and power loss. With the input dc voltage of 36 V, modulation index of 0.5, and shoot-through duty ratio of 0.45, both the configurations are simulated in the MATLAB/SIMULINK environment to validate the theoretical concepts. The harmonic profile of both the topologies is presented. The experimental results are presented to validate the simulation results. The detailed analysis shows that one of the single-stage qSBI topologies namely Embedded type qSBI (EqSBI) possesses the superior features compared to the traditional dc/dc-boosted inverter topologies.
